我们通常采用最多的是圆柱形管状钥匙锁,平扁牙花钥匙锁，叶片钥匙锁。但是钥匙的种类有1000种以上。锁的安全防破坏性能取决于锁体材料强度。安全性取决于钥匙的号码数量（号码有不同高低变化。）钥匙牙花变化少于20种以下保险性不高，另在100种至1万种变化。数量越多，可靠性和开启的可能性越少，越安全。一般高低变化较多的圆柱管状锁，其安全性高于其他平扁片状锁。

 

1．电源开关锁

电源开关锁是通过机械装置，利用钥匙开启、转动达到带动后端绝缘电源部位开、关通断，开关自动复位，开关分段控制，起到安全性、绝缘性的效果。随机钥匙可以1个位置取下，可以2、3、4个位置取下。特别在高新科技产品和自动化产品的应用上。起到重要的作用。主要安装尺寸有Φ8M/M和Φ150M规格。

 

2．转舌锁和机械锁

该类型锁主要用途在门、柜箱等开启，关闭。用钥匙带动后端铁板（舌头形）固定二分体件的连接起到密封和防尘防盗的作用。主要用在工业、家用、民用产品上。通用开关距离需要45°- 360°不等。主要安装尺寸有Φ10-Φ100不等。

 

3．怎样选择钥匙开关锁

钥匙分相同号码：一把钥匙能打开全部的锁，这样工业上便于操作。但安全性较差。钥匙分不相同号码：即100种钥匙不能相互打开。一把钥匙只能解开一种锁。不能开另一种锁。主要用在需要防盗或安全性比较强的产品上。但也可以定制特种规格的锁和钥匙。

 

Lock choice

We usually use cylindrical tubular key lock, flat key lock, leaves key lock. But the key types are more than 1,000 kinds. Anti- damaged properties of locks depends on the strength of the material. Security depends on the key numbers (numbers have different levels change.) The locks lack of security when the type of key teeth is less than 20 kinds. From 100 to 10,000 kinds of changes. The more reliability and the possibility of opening the less, the more security. More changes in the general level of the tubular cylinder locks, it is safe than other flat key locks.

 

1. Switch lock

The switch lock can become safety by the means of mechanical devices, led the back insulation part open、cut off, automatic reset , sub-control by using keys to open. Keys can be pulled out at 1 position or 2,3,4 positions. Especially in the high-technology products and automation products applications. Main dimensions areΦ8mm andΦ150mm

 

2. Cam lock & Mechanical lock

The type of lock is used for the door, counter bins opening and closing. Led by key back-end monolithic (tongue-shaped) fixed point of the connecting pieces of a security seal and the role of dust. Mainly used in the industrial, domestic, civilian products. Generic switching distance needs 45°- 360°range. Main dimensions areΦ10mm-Φ100mm.

 

3. How to choose & master keys

Keys in the same number: One key can open all the locks, such industrial efficiency of operation is poor in security. Keys are not the same numbers: 100 kinds of keys could not open each other. A key to a lock can only open one lock than other locks. Mainly used in anti-theft or security needs a strong products. But it may also be customized specifications for the special lock and key.
